 1.圓球

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidSphere(0.3, 30, 30);

    glutSwapBuffers();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week14");

    glutDisplayFunc(display);

    glutMainLoop();

}

2.網狀球體

#include <GL/glut.h>

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutWireSphere(0.3, 12, 5);//半徑、縱切、橫切

    glutSwapBuffers();

}

void timer(int t)

{

    glClearColor( 1,0,0,0);

    display();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week14");

    glutDisplayFunc(display);

    glutTimerFunc( 4000, timer, 0);

    glutMainLoop();

}

3.定時旋轉方塊

#include <GL/glut.h>

int angle = 0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    //glutWireSphere(0.3, 12, 5);//半徑、縱切、橫切

    glPushMatrix();

        glRotatef(angle, 0,0,1);

        glutSolidCube(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

void timer(int t)

{

    glutTimerFunc( 30, timer, t+1);

    angle++;

    display();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week14");

    glutDisplayFunc(display);

    glutTimerFunc( 4000, timer, 0);

    glutMainLoop();

}

4.重複旋轉方塊

#include <GL/glut.h>

int angle = 0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    //glutWireSphere(0.3, 12, 5);//半徑、縱切、橫切

    glPushMatrix();

        glRotatef(angle, 0,0,1);

        glutSolidCube(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int diff = 2;

void timer(int t)

{

    glutTimerFunc( 20, timer, t+1);

    angle+=diff;

    if( angle > 180) diff = -diff;

    if( angle < 0)   diff = -diff;

    display();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week14");

    glutDisplayFunc(display);

    glutTimerFunc( 4000, timer, 0);

    glutMainLoop();

}

5.直接重複選轉方塊

#include <GL/glut.h>

int angle = 0;

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    //glutWireSphere(0.3, 12, 5);//半徑、縱切、橫切

    glPushMatrix();

        glRotatef(angle, 0,0,1);

        glutSolidCube(0.3);

    glPopMatrix();

    glutSwapBuffers();

}

int diff = 2;

void timer(int t)

{

    glutTimerFunc( 20, timer, t+1);

    angle+=diff;

    if( angle > 90 || angle < 0) diff = -diff;

    display();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week14");

    glutDisplayFunc(display);

    glutTimerFunc( 0, timer, 0);

    glutMainLoop();

}

6.選轉方塊手臂

#include <GL/glut.h>

int angle = 0;

void drawArm1()

{

    glPushMatrix();

        glScalef(1, 0.5, 0.5);

        glColor3f(1,0,0); glutSolidCube(0.3);

    glPopMatrix();

}

void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    //glutWireSphere(0.3, 12, 5);//半徑、縱切、橫切

    glPushMatrix();

        glColor3f(1,1,1); glutSolidCube(0.4);//身體白

        glPushMatrix();

            glTranslatef(-0.2, +0.2, 0);

            glRotatef(angle, 0,0,1);

            glTranslatef(-0.15, 0, 0);

            drawArm1();

        glPopMatrix();

    glPopMatrix();

    glutSwapBuffers();

}

int diff = 2;

void timer(int t)

{

    glutTimerFunc( 20, timer, t+1);

    angle+=diff;

    if( angle > 90 || angle < 0) diff = -diff;

    display();

}

int main(int argc, char** argv)

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("week14");

    glutDisplayFunc(display);

    glutTimerFunc( 0, timer, 0);

    glutMainLoop();

}
